“…Among a variety of fluorophores, phenylimidazole fluorophore is one of the most famous dyes with a rigid large planar structure and the structure can be flexibly modified. In addition, phenylimidazole has high quantum yield and stable fluorescence and thermodynamic properties under photo-oxidation conditions so that it has a wide application in photochemistry and some probes based on phenylimidazole have been developed [27,28,29,30,31]. Moreover, most of these probes response to Hg 2+ ions through single emissions intensity change by fluorescence quenching or enhancement, which is likely to be limited to temperature, solvent polarity, medium characteristics, excitations power, dye concentrations, and other factors.…”

“…Fluorescence microscopy is a widely used and very versatile tool for analyzing molecules and intermolecular interactions at low concentrations [1]. Many publications focus on fluorescence imaging but not the detection of intensities from samples that cannot be studied using conventional fluorescence spectrometers [1,2]. The detection of fluorescence intensity or subtle changes in intensity due to interactions can be difficult at times due to sensitivity and resolution limitations as well as the short excitedstate lifetime of many fluorophores.…”
